It seems like the solution to that would be to use multiple types of housing construction within the same city, and then people can choose one suitable to their situation. And to make other sensible choices like to put heavy appliances on the ground floor.
Yes. The comment you responded to earlier said "It wouldn’t be bad for one off where the lot was oddly shaped but to have that as a default for attached homes isn’t great."
And what I'm saying is the opposite. It's fine for it to be common as long as there are still enough single floor dwellings for the people who need them.
There should be all kinds of everything. A city should be a massively diverse cacophony of individual choices. That means that finding exactly what you want is going to exclude >90% of the properties -- but means that finding exactly what you want is going to be possible.
